Getting it into your agent

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00057 | $0.00414 |
| Opus 5 | $0.00028 | $0.00207 |
| Sonnet 5 | $0.00011 | $0.00083 |
| Haiku 4.5 | $0.00006 | $0.00041 |
Grade A, and why
viz scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 7d ago.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.
Nothing flagged
None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.
What it actually says
vs-token-safer — open the dashboard
Start the local dashboard server and open it in the browser. It is local-only (binds 127.0.0.1,
serves a fully self-contained page + the locally-vendored Three.js — nothing leaves the machine) and
opt-in (it is NOT the always-on MCP server; it runs only while this command's process is alive).
Do this:
-
Run the dashboard in the background (it's a long-running server), opening the browser automatically:
vts serve --open --projectPath "<the current project root>"If
vtsis not on PATH, run the bundled CLI instead:node "$CLAUDE_PLUGIN_ROOT/server/cli.js" serve --open --projectPath "<the current project root>"Launch it with
run_in_background: trueso it keeps serving across turns. Pass--port <N>if 8731 is taken (the error message says so). -
Tell the user the URL it printed (e.g.
http://127.0.0.1:8731/) and that it's local-only. -
If the include-graph panel is empty, note that the graph fills in after some searches — they can run
vts warmup --projectPath <root> --backend <clangd|typescript|…>or just keep using the search/nav tools (each search records into the warm-set + include-graph).
To close it later, use /vs-token-safer:viz-stop (or vts serve --stop, or Ctrl-C the process).
What this file has done since we first saw it
Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

viz is a command published in the GitHub repository JSungMin/vs-token-safer (11 stars, last pushed 4d ago), licensed MIT. It adds 57 tokens to every session and 414 once invoked, about $0.0003 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
